I 'tried out' a 'suicide hub' 18 years ago....long before the term 'suicide hub' (or even 'fixie' for that matter existed). It wasnt a 'testing the waters' thing, it was a 'this is what many people have been doing for 60 years' thing.
anyway, I'm still riding a freewheel hub 18 years later and have never had an incident.
